The correct answer is: A. will have eliminated
The sentence is in the future perfect tense, which is used to talk about an action that will be completed by a specific time in the future. In this case, the action is “eliminating Chelsea from the Champions League.” The future perfect tense is formed with the auxiliary verb “will have” and the past participle of the main verb, which in this case is “eliminate.”
The other options are incorrect because they do not use the future perfect tense. Option B, “is eliminating,” is in the present progressive tense, which is used to talk about an action that is happening now. Option C, “has been eliminated,” is in the past perfect tense, which is used to talk about an action that was completed before a specific time in the past. Option D, “eliminates,” is in the simple present tense, which is used to talk about an action that happens regularly or repeatedly. Option E, “will be eliminating,” is in the future progressive tense, which is used to talk about an action that will be happening at a specific time in the future.
In conclusion, the correct answer is: A. will have eliminated
